संदीप्ति

कम तापमान पर उत्सर्जित होने वाले प्रकाश को संदीप्ति (Luminescence) कहते हैं। यह वस्तुतः 'शीत वस्तु विकिरण' (cold body radiation) का एक प्रकार है।

संदीप्ति के प्रकार 
 जीवदीप्ति (Bioluminescence) - by a living organism
 रासायनिक संदीप्ति (Chemoluminescence) - resulting of a chemical reaction
 विद्युतरासायनिकसम्दीप्ति (Electrochemiluminescence) - by an electrochemical reaction
 Crystalloluminescence, produced during crystallization
 विद्युतसंदीप्ति (Electroluminescence) - in response to an electric current passed through it
 कैथोडसंदीप्ति (Cathodoluminescence) - where beam of electrons impacts on a luminescent material such as a phosphor
 यांत्रिकसंदीप्ति (Mechanoluminescence) - resulting from any mechanical action on a solid
 Triboluminescence, generated when bonds in a material are broken when that material is scratched, crushed, or rubbed
 Fractoluminescence, generated when bonds in certain crystals are broken by fractures
 Piezoluminescence, produced by the action of pressure on certain solids
 प्रकाशसंदीप्ति (Photoluminescence), absorption of photons causing re-radiation of photons
 स्फुरदीप्ति (Phosphorescence) - delayed re-radiation
 प्रतिदीप्ति (Fluorescence) - where the emitted photons are of lower energy than those absorbed
 रेडियोसंदीप्ति (Radioluminescence) - produced in a material by the bombardment of ionizing radiation
 ध्वनिसंदीप्ति (Sonoluminescence) - from imploding bubbles in a liquid when excited by sound
 तापसंदीप्ति (Thermoluminescence) - when absorbed light is re-emitted on heating.

अनुप्रयोग 
 Light Emitting Diode's (LED's) emit light via electroluminescence
 Phosphors, emitting light when irradiated by higher-energy electromagnetic radiation or particle radiation
 Phosphor thermometry, phosphorescence can be used to detect the temperature of an object.
